ORDERABLE LOOKUP ORDERABLE ITEMS    ICR (6817)

This integration agreement will allow the DSS CyberREN
to check whether the primary node exists, as well as look up internal entry
number with NAME field through the use of "B" cross reference. No direct reads
or writes to the globals will be done. The primary purpose of the ICR is to
check whether the node exists using $D, and calculate the internal entry
number given its name.
